In order to insure. effective and satisfactory operation of acentrifugal separator, care must be taken to prevent the machine frombeing subjected to any shocks.

It has been proposed to eliminate shocks in a centrifugal separator bydistributing the material to be centrifuged over the entire width of thecentrifugal drum lor bowl in a uniform manner. Several forms ofapparatus have been proposed for this purpose. For instance, one suchapparatus comprises a, distributing pipe extending into the interior ofthe bowl, and having an opening extending lengthwise of said pipe andacross the entire width of the bowl. By means of this arrangement, morematerial will pass through a portion of the opening nearest the feedingpoint, than will the portion of the opening on the outer end of thepipe. In order to eliminate this condition, it h'as been proposed tomake this opening of variable width so that the opening diverges towardsthe outer end of .the pipe. However, I have found that lin apparatus ofthis kind, the opening hasa tendency to clog especially near the innerend of the pipe where the opening is narrowest.

One object of the present invention is to provide a new and improveddevice for uniformly distributing the material to be centrifuged in theinside of the centrifugal drum.

As an important feature of the present inve tion,- there is employed,for introducing the material, a distributing member having the outletend thereof extending substantially over the entire width of the bowland having a series ofV diverging channels receiving substantially equalamounts of material, and acting to uniformly distribute the materialthroughout the width of the outlet end.

In the accompanying drawing, there are shown for purposes ofillustration, two embodiments of the presenty invention. Inthe drawingFig. 1 is a vertical section taken through a centrifugal machine, andshowing one form of distributing device embodying the present invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a front elevation ofanotherform of distributing deviceembodying the present invention, and

Fig. 4 is a section taken on line 4-4of Fig. 3.

The embodiments of the present invention are illustrated in connectionwith a centrifugal drum 10 mounted on a horizontal shaft 11 which may bedriven from any suitable source of power. The material to be centrifugedis introduced through 14, 1932, Serial No. 605,153, and0 (ci. 21o-cs) apipe 12 passing through an opening 13 at-one end of the drum 10, andleading into the interior of said drum. I have shown the end of the pipe12 terminating substantially midway between the ends of the drum 10, andconnected to the inlet end of a distributing member depending from saidpipe. As ,an important feature of the invention, the distributing memberhas a pluralvity of fiared or diverging channels, the aggregate outletends of which extend substantially across the entire width of the drum10.

- Inthe form shown in Figs. 1 and 2, the dis! tributing member comprisesa fan shaped tubular member 14 subdivided by a plurality Aof divergingguide members or ribs 15 to form a Vseries of ad- 70 jacent channels 16each tubular in shape. These channels are iiared towards the outlet endof the member 14 in'accordance with the are of said .member, and havingsubstantially equal widths at their vinlet and outlet ends. It isadvantageous 76 that the inletends of the channels 16 be spaced from theoutlet end of the pipe 12 so as to leavel a manifold chamber 17 fromwhich the material may be distributed equally to the various channels16. By means of this distributing member, the so material which isdelivered by the pipe 12 to the manifold chamber and then to the inletsof the various channels 16, is thereby uniformly! distributed across theentirewidth of the inside of the drum 10.

In Figs. Sand 4 is shown another form in which the distributing memberis in the form of a fan shaped plate 18 connected to the outlet end ofthe pipe 12, and having connected thereto a series of guide webs 19forming a plurality ofared chan- 90 nels 21'in the form of troughsthrough which the material is Auniformly distributed and delivered intothe interior of the centrifugal drumllO. The plate 18 may form anintegral part of the pipe 12 and extends therefrom in a direction topermit `95 gravitational flow of material thereover. l

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:-

1. A centrifugal machine including a rotatable 10 drum, a supply pipetherefor, and a distributing member in said drum, comprising a fanshaped tubular member having the smaller inlet end thereof connected tosaid pipe, and having the outlet end thereof extending oversubstantially 305 the entire width of the drum, said member beingdivided into a plurality of adjacent diverging tubular channels with theinlet ends thereof ad# jacent to the outlet end of said pipe, wherebythe 'material supplied through said pipe is unito n@ distributed to saiddiverging channels, and delivered into the interior of the drumsubstantially uniformly along substantially the entire width of thedrum'.

2. A -centrifugal machine including a rotatable drum, a supply pipetherefor, and a distributing member in said drum, comprising a fanshaped tubular member having the smaller inlet end thereof connected tosaid pipe, and having an elongated outlet end extending substantiallyacross the entire width of the drum, and guide members in said tubularmember dividing said tubular member into a plurality of adjacent tubularchannels extending from a region close to -the inlet of said tubularmember towards the outlet of said latter member, whereby the materialsupplied through said pipe is uniformly distributed to said channels anddelivered into the interior of the drum substantially uniformly alongsubstantially the entire width of the drum.

3. A centrifugal machine including a rotatable I drum, a pipe forconducting material to be treated i into the interior of said drum, anda member drum mounted on a horizontal axis, a supply pipe therefor, anda distributing member in said drum for uniformly distributing materialsubstantially over the entire width of the drum. and comprising a fanshaped plate having the narrower end adapted to receive material fromsaid pipe and the wider delivering end extending across substantiallythe entire width of said drum, said plate having a plurality of guidemembers forming therewith a plurality of adjacent diverging trough-likechannels extending from a region close to said pipe towards the outerend of said plate, said plate extending in a direction to permitgravitational flow of the material from said pipe along said trough-likechannels, whereby the material supplied through said pipe is uniformlydistributed to said channels and delivered into the interior of the drumsubstantially uniformly along substantially the entire width of thedrum.

5. A centrifugal machine including a rotatable drum, a pipe forconducting material to be treated into the interior of said drum, and aplurality of adjacent channels having their inlet ends close to theoutlet end of said pipe for receiving material to be centrifuged fromsaid pipe, said channels diverging at their outlet ends, and said outletends collectively extending along substaniially the entire length 'ofthe-drum, whereby the material supplied through said pipe is uniformlydistributed to said diverging channels and delivered into the interiorof the drum substantially uniformly along substantially the entirelength thereof.
